Design of a wasp-inspired biopsy needle capable of self-propulsion and friction-based tissue transport by Jette Bloemberg, Suzanne van Wees, Suzanne van Wees, Vera G. Kortman, Aimée Sakes

“…Inspired by the ovipositor of parasitic wasps, which resists buckling through self-propulsion and prevents clogging via friction-based transport, research has led to the integration of these functionalities into multi-segment needle designs or tissue transport system designs. …”

Non‐Reciprocity, Metastability, and Dynamic Reconfiguration in Co‐Assembly of Active and Passive Particles by Ahmed Al Harraq, Ruchi Patel, Jin Gyun Lee, Ope Owoyele, Jaehun Chun, Bhuvnesh Bharti

“…Here, out‐of‐equilibrium assemblies of non‐motile isotropic passive and metal‐patched motile active particles are formed by overlapping bulk interactions with directed self‐propulsion. An external alternating current (AC) electric field generates concurrent dipolar and induced‐charge electrophoretic forces between the particles which are evaluated using microscopy. …”
